Subject: Add libpciaccess and remove xf1bpp and xf4bpp support.
X-Git-Url: http://gitweb.freedesktop.org/?p=xorg/driver/xf86-video-vga.git;a=commitdiff;h=97e2d12548921d92b6dc2dcce8abee48f25981d2
Add libpciaccess and remove xf1bpp and xf4bpp support.
The driver is not fully functional, starts at 320x200, but may require
running something like vbetool post before starting the X Server, and does
not restore console as usually linux consoles use vesafb, but should work
correctly if console is in a "standard vga mode".
